PUSH BAR FOR METAL DooRs l Filed April 9; 1957 7,2/0/1/,45 7.' fyef INVENTOR.
' @Trae/V515 PUSH iBAR EUR DDORS Metal Molding Co., Los Angeles, Calif., a corporation of California 4 This invention relates to building hardware, and has particular reference to a push bar for metal frame doors.
One of the principal objects of this invention is to provide a novel push bar construction for attachment to doors of the metal frame type, the push bar being provided with means for a permanently rigid attachment thereof.
Another object of this invention is to provide a push bar assembly adapted to be attached to a metal frame door with the use of only a single screw, which is located on the hinge side of the door.
Another object of this invention is to provide a'novel push bar which is unhanded, i. e., capable of attachment to either side of a leftor right-handed swinging door.
Still another object of this invention is to provide a novel push bar of simple construction and pleasing appearance, and which can be installed on the job site to meet the requirements of the user.
Other objects and advantages of this invention, it is believed, will be readily apparent from the following detailed description of a preferred embodiment thereof, when read in connection with the accompanying drawings.
In the drawings: Figure 1 is a perspective view of a door having attached thereto the push bar of the present invention.
Figure 2 is a sectional elevation taken substantially on the line 2--2 of Figure 1.
Figure 3 is a fragmentary sectional view similar to Figure 2 but illustrating the initial position of the operating or swinging end of the bar prior to final assembly.
Figure 4 is a fragmentary sectional view similar to Figure 3 but illustrating the position of the operating end of the bar after final assembly.
Doors of commercial and residental buildings are fre quently equipped with so-called push bars for assisting persons to open and close the door by applying pressure to the bars in the appropriate direction. Such bars are frequently used on swinging doors so that the door may be opened from either direction by pushing or pulling the push bar on that side of the door. In the past, it has often been the practi-ce to secure the ends of such push bars to the door by means of screw plates mounted on the opposite sides of the door. Such screw plates, however, are not only very visible and objectionable from the appearance standpoint, but tend to become loosened after repeated use, causing the bar to rattle.
The push bar construction of the present invention eliminates the disadvantages of these prior doors by entirely dispensing with screws on the operating end of the bar. This end of the bar is provided with a spring hook member which is inserted through a hole in the door stile, the end of the hook contacting the inside of the stile and maintained thereagainst under tension when the assembly is completed by attaching the other end of the bar to the hinge stile with a single screw. Thus, a permanently rigid attachment is provided. The number of parts is not only reduced to a minimum, but `these parts are for the most United States Patent "part concealedtrom view. 'Theinished pushbar lcon- A,struction,ismoreover, .of clean, vmodern-appearing 'de- '.Sign wit'hnqprojecting parts or separate attachment mem- .bersto mar, thelbeauty of its appearance.
Referring now ,to the drawings,y a conventional [door v'10 `is, 'equilgvapec'l with the ,.pu'sh ,bar assembly .11 ofthe present invention. -The doorisof conventional construction, vfthat YshownIhavirlg an aluminumSframe including vvstileS.or upright frame members 12 and `13-interconnected b'yhoiizontal members 16 and 17 at top and'bottom, respectively, these enclosing a glass central panel 20.
The push bar is formed of a single piece of bar stock including a straight, elongated main body portion 25 integral at one end with a portion 26 bent at right angles thereto. Integral with the other end of the body portion is an inclined portion 27 terminating in an end portion 28 parallel to but offset from the body portion. The portion 26 is provided with a central bore 30 into which is driven the shank of a steel spring hook member 31. The inside of the portion 26 is indented as at 32 to hold the hook member in place. The portion 28 is provided with a countersunk hole 33.
For assembly of the push bar 11, the hinge stile 13 is provided with a tapped hole 40 and the other stile is provided with an aperture 41. The hook member 31 is inserted through this aperture as shown in Figure 3, the push bar assuming the phantom line position of Figure 2. With the end of the hook member in contact with the inside wall of the stile 12, the push bar is forced into the final, solid line position of Figures 2 and 4 by turning down the single attachment screw 45. This places the hook member and the bar under tension to firmly attach the push bar to the door in a permanent fashion, removing all possibility of rattles.
While only a single push bar is illustrated, it will be understood that a pair of bars may be used on a single door if desired, as would be the case with a doubleswinging door.
From the above description it will be understood that only a single attachment screw is required, and this screw is located at the hinge end of the door, remote from the operating end of the push bar. This construction, when combined with the spring tension assembly, provides a highly ornamental device, yet one which is not subject to loosening under conditions of prolonged use. Moreover, inasmuch as only one hole is required in each stile, no factory fabrication is necessary, and the bar can be installed at the job site to meet the requirements of the user.
Having fully described my invention, it is to be understood that I do not wish to be limited to the details set forth, but my invention is of the full scope of the appended claims.
I claim:
1. In combination with a door having a hollow hinge stile and a hollow outer stile, a push bar assembly comprising a bar formed into a straight, elongated body member, a portion at one end thereof bent at an angle to said body member, a spring hook member secured to said portion, said hook member being inserted through an opening in said outer stile, the end of said hook member contacting the inner surface of said stile and means for attaching the other end of said bar to said hinge stile with said hook member placed under a condition of tension.
2. In combination with a door having a hollow hinge stile and a hollow outer stile, a push bar assembly comprising a bar formed into a straight, elongated body member, a portion at one end thereof bent at an angle to said body member, a spring hook member secured to said portion, said hook member being inserted through an opening in said outer stile, the end of said hook member contacting the inner surface of said stile, the Other end of said bar being provided with an inclined portion terminating in an end portion parallel to said body portion but oiset with respect thereto, and means for attaching the said other end of said bar to said hinge stile with said hook member placed under a condition -of tension. l
3. In combination with a door having a hollow hinge stile and a hollow outer stile, a push bar assembly comprising a bar formed into a straight, elongated body mem-A ber, a portion at one end thereof bent at right angles to said body member, a spring hook member secured to said portion, said hook member being inserted through an opening in said outer stile, the end of said hook member contacting the inner surface of said stile, the other end of said bar being provided with an inclined portion terminating in an end portion parallel to said body portion but offset with respect thereto, and means for attaching the said other end of said bar to said hinge stile with said 5 hook member placed under a condition of tension.
